Title: Method of producing portions of tobacco and apparatus for carring this method into effect
IPC: B65B1/10
Filed: 1965-07-08
Abstract: 1,074,370. Feeding tobacco. K. KÍRBER. July 8, 1965 [July 16, 1964; Sept. 10, 1964], No. 28937/65. Heading A2C. A method of producing portions of tobacco is characterized in that an annular tobacco rod is built up from tobacco supplied with a movement having a radially outwardly directed component and a tangential component and is divided into circumferential sections. In the embodiment shown in Fig. 5 weighed portions of tobacco are periodically delivered into the hopper 117 of a radial centrifuge distributer 223 from a weighing container 208 forming part of a balance which controls electrically a motor 215 feeding tobacco 204 into the container by rolls 205, 206 and 216. The distributer 223 comprises a casing 105 within which are mounted for rotation about an axis 122 two walls 103 and 104, the walls being driven by means of pulleys 108 and 109 respectively. The walls have ribbed portions 110 and 111 and define a channel 101. The wall 103 is perforated at 112 to afford communication with a chamber 113 to which the suction tube 115 of a blower 116 is connected. A carrier member 120 is also mounted for rotation about the axis 122 and driven by a spur gear 123. The periphery of the carrier member 120 is provided with a number of six-bladed shafts 125 disposed at equal angular spacings around the carrier, separated from each other and enclosed by rings 132 so as to form a number of compartments around the outlet for the channel 101. The walls 103 and 104 rotate at high speed and distribute the weighed portion of tobacco equally between the blades 126 of the compartments. An electrical control circuit is provided which, after the distribution of tobacco into the compartments, operates step by step drives 136 and 137 which include magnets, as 135, and co-operating armatures which rotate the blades 126 through 60 degrees as each compartment comes above discharge ducts 133 and 134, thus discharging the tobacco through holes, as 130, 131, provided for each compartment, into the ducts 133 and 134 on to conveyers 144 and 145. During this operation no tobacco is fed into the hopper 117 and the carrier 120 rotates step by step until all compartments have been emptied. A new weighed tobacco charge is then automatically introduced into the hopper 117. In a second embodiment, Fig. 1 (not shown), the compartments are formed by walls in the distributer casing and each one is connected to a discharge duct. When the compartments are full suction is applied to the discharge ducts to withdraw the portions of tobacco from the compartments against the action of spring loaded retaining flaps provided at the base of each of the compartments.

[Classes 28(i) and 49] Apparatus for the preserving or treatment of fruit, vegetables or animal products with a solution of sugar, salt or the like comprises a battery of vessels 1-19 in series and each provided with removable superposed trays 29 (not shown). When preserving fruit, for example, the fruit, after blanching, is placed in the trays to a limited maximum height to avoid crushing and to facilitate permeation. A saturated sugar solution then flows under pressure into vessel 1 permeating the fruit completely with sugar, after which, at a reduced density, the solution passes into vessel 2 and so on throughout the series. The solution in its final dilute state is collected in a container 24 and re-used after boiling and strengthening. The completely permeated contents of vessel 1 are removed after isolation of the vessel by means of cocks 32, 33, 40, and the saturated solution supply is diverted to vessel 2, the contents of which now become completely permeated. After recharging with fresh fruit, vessel 1 by the operation of cocks 37, 39, 40 becomes the end one of the series and the sequence is carried on as required.

Title: Improvements relating to pumping systems having several centrifugal pumps arranged in parallel
IPC: F04D13/14
Filed: 1948-11-11
Abstract: 641,928. Centrifugal pumps. SULZER FRERES SOC. ANON. Nov. 11, 1948, No. 29295. Convention date, Nov. 14, 1947. [Class 110(i)] [Also in Group II] A pumping system comprises several centrifugal pumps in parallel of which one or more can be shut down while the others continue to operate, the pumps delivering liquid through separate pipes up to a highest point whereat, or whereafter, the pipes enter a common delivery conduit. The pipes or the conduit are provided with ventilating means arranged not lower than the said highest point, and the height of the latter above the static liquid level in the conduit is not less than the resistance head in the conduit when one pump is shut down. Three centrifugal pumps, one of which is shown at 2, draw liquid from a sump 19 and deliver if through separate pipes 10 to a delivery conduit 12, 13. The part 12 has a cross-sectional area at the point of entry of the pipes 10 which is at least 1.5 times that of the part 13. The pipes 10 may have terminations 17 arranged to impart to the liquid tangential components all in the same direction, and axial components which are not more than 10 times as great as the tangential components. The resultant swirl imparted to the liquid separates out entrained air, which escapes through a ventilation pipe 14. To take into account the amount of air which nevertheless remains entrained, it is desirable to make the height above the static liquid level of the highest point 11 of the pipes 10 at least 1.2 times the resistance head in the delivery conduit 12, 13 which would occur if one of the pumps were shut down and the liquid were wholly free of air. The driving motors 4 are controlled by a switching device 9 controlled by a float 7, whereby the pumps are shut down, one by one, as the level 6 falls. The device can contain a time switch which pericdically changes over the connections to the motors 4 so as to ensure uniform use of the pumps. When all three pumps are operating, the liquid level will generally be above the point 11. If one of the pumps is shut down, liquid initially flows back through the pump, so cleaning it. Eventually the reduced flow causes the liquid level to fall below the point 11, so that the reversed flow ceases. If the delivery conduit gets sufficiently fouled, the resultant increase in the resistance head causes a warning outflow through the end 16 of the pipe 14 and also a return flow through the shut-down pumps. The level 6 then rises sufficiently to put all the pumps into operation until the level 6 has again dropped, and this process continues until the conduit is clear again. Valves 18 are provided to enable individual pumps to be overhauled while the others are operating. The pumping system may be closed and subjected to a gas pressure different from atmospheric,

Filed: 1919-11-25
Abstract: 145,346. Israel, A. J. Nov. 25, 1919. Coating-machines.-In lining metal pipes by centrifugal deposition of cementitious material, the ends of the pipe are partially closed while the pipe is partially filled with a mixture of cementitous material and water, the surplus water being run off after the lining has been formed by a preliminary rotation, and rotation continued thereafter until the lining is set. As shown in Fig. I., the pipe end is partially closed by a flat ring 3 held against the pipe end by bolts 4 engaging a split clamping ring 2 secured to the pipe. Within the grooved aperture 6 corresponding to the thickness of the lining, is seated a split ring 8 regulating the initial level of the fluid material. After the lining has been formed by a preliminary rotation, the ring 8 is removed by insertion of a tool in the opening 9 and the surplus water run off, the rotation being then continued until the lining is set. The ring 3 and clamp 2 are then detached. A modified attachment suitable for pipes with threaded ends, comprises an externally threaded flanged cylinder connected to the threaded pipe end by an internally threaded sleeve, the split ring being seated in the grooved aperture as before. The pipe may be rotated on a bed as shown in Fig. III., comprising a fixed head stock 14 and traversible tail stock 15 provided with rotatable hollow mandrels 18 terminating in hollow chucks 19 arranged to grip the pipe ends. One mandrel is driven by means of a belt pulley 20.

Abstract: 1291754 Actuating brakes; adjusting for wear DAIMLER BENZ AG 17 June 1970 [25 June 1969] 29451/70 Heading F2E  An assembly actuable to move brake shoes into contact with a brake drum comprises a rotatable brake shoe operating cam 4, a friction member in the form of a plate spring 5 disposed between the cam 4 and a control plate 6 which is rotatable by a fixed angular distance 11 with respect to a rigid port 1 of the assembly. As shown, the cam 4 is rotatable by way of a lever 12, preferably with air servo assistance, and an overrun-clutch device 13 which in the direction of brake actuating movement of lever 12 locks to rigidly connect the lever 12 with a camshaft 2 of the cam 4. The control plate 6 and the friction member 5 rotate with the cam-shaft 2 through the angular distance 11 until spherical guide members 9 reach the end of guideways 10 in the control plate 6. If the brake shoes are not in contact with the brake drum at this juncture, then further rotary movement of the cam-shaft 2 causes the friction member 5 to slide on the control plate 6 and a step 3 between the camshaft 2 and the cam 4 while the control plate 6 remains stationary. On releasing the lever 12, the overrun device B unlocks and the cam-shaft 2 is rotated in the release direction by a spring, whilst the control plate 6 is rotated through the angular distance 11. The brake cam 4 is thus rotated backwards through a distance which is less than its forward rotation and the assembly is adjusted for shoe lining wear.

Abstract: 695,306. Insulators ; printed circuits. STRONG, H. V., and EISLER, P. Nov. 30, 1951 [Dec. 1, 1950], No. 29515/50. Class 36. Metallized insulators are made by stacking interleaved metal foil laminµ and thin insulating laminµ so that parts of the metal laminµ are not covered by insulating laminµ and vice versa and treating the stack so as to unite the parts of the metal laminµ that have no insulation therebetween, and to unite the parts of the insulating laminµ that have no metal therebetween. A cylindrical bushing insulator 17 (Fig. 3) having metal rings 18, 19 at either end may be made by winding a strip 10 of paper, impregnated with an uncured or partly cured resin, round a mandrel for a few turns. Tapes 11, 12 of tinned metal are then cemented to each side of strip 10, the paper being perforated near its edges as at 14 and the metal tapes being perforated near their inner edges as at 15, and the winding continued for a few turns. The metal tapes are then given a few more turns and the ends fastened temporarily. The assembly is heated so that the layers of foil unite where they are not interleaved by paper and the resin is cured so that the insulation is united together where the insulating laminae are not separated by metal. A bushing insulator 28 in which the metal parts are in the form of internal and external sleeves 29, 30 (Fig. 8) may be produced by stacking annular insulating laminae interleaved with large and small annular metal laminµ between which there is a substantial annular gap. The laminae are perforated so that on heating and pressing the stack alternate layers are united through the perforations. The laminµ may be produced by punching or stamping, or by any of the methods described in Specifications 639,111, 639,178, 639,658, or 644,565. Alternatively, a repeat pattern of the metal laminae may be printed on one side of a metal foil with an etch resistant ink. Representations of the insulating laminae are printed on the other side of the foil, using a sticky ink, so that the two patterns register correctly. The latter print is sprayed with flock, which adheres to the ink, and the whole side lacquered. The foil is etched to remove the exposed parts on the first side and after washing the etchresistant ink and the lacquer are removed. The coated foils are then stacked and pressed under heat, the single insulators being finally punched out of the completed stack. The method may be employed for mechanically reinforcing the bond between the metallic patterns and insulating supports in printed circuits and for the production of a complete cover-plate and terminal board for hermetically sealed equipment.

Abstract: 537,109. Knitting - machines. MELLOR, BROMLEY, & CO., Ltd., BROMLEY, T. C., and SHORTLAND, A. Nov. 8, 1939, No. 29648. [Class 74 (ii)] The fabric gripping rollers of a knitting- machine take-up device' are driven independently so that, should they be forced apart by a thick place in the fabric, they are still driven and continue to function normally. The rollers 1, 2 are carried in brackets 3, 4 on an horizontal gear 5 and revolve in unison with the needle cylinder. One of the rollers is supported by elongated openings in the brackets 3, 4 so that it can move away from the roller 1, if required, against spring pressure. The extreme ends of each roller 1, 2 are formed with ratchet teeth 21 acted on by pawls such as 22. Each pawl is common to both rollers and remains in engagement with both sets of ratchet teeth when the rollers are separated abnormally. Each pawl is pivoted at 24 to a slide 23 reciprocated by a cam roll 27, which runs on a track 6a. If the pawls at opposite ends of the rollers 1, 2 come into action alternately, the rollers are driven almost continuously. In a modification, the rollers 1, 2 are driven by a cam ring the inclination of which can be adjusted, by hand or mechanically, to vary the rate of drive. Specification 357,323 is referred to.
